ETS-Lindgren’s EMCO Model
3143B BiConiLog is a hybrid
antenna that combines innovative
design, compact size, and excellent
performance. This antenna enables
users to measure a frequency range
of 30 MHz to 1 GHz in one sweep,
negating the need for multiple
antennas and time-consuming
equipment setup. Accuracy and
repeatability are improved, while
time and money are saved.
This BiConiLog is designed as
a dual-purpose antenna that can
be used for both immunity and
emission testing.
This model includes a stinger
mount as standard equipment.
Individual antenna calibration data
is provided for emission testing.
FEATURES
Frequency Range
The Model 3143B frequency range
covers from 30 MHz to 1 GHz.
This frequency range covers the
necessary range of emissions testing
on a traditional OATS/semi-anechoic
chamber setup.
VSWR Levels
Typical VSWR for the 3143B is
>3:1 above 70 MHz, an excellent
level at this low frequency for an
antenna this size.
Emissions and Immunity Antenna
Emission measurements can be
performed without having to change
antennas.
For immunity measurements, the
3143B covers the typical 80 MHz to
1 GHz range.
Flexible Mounting System
The Model 3143B comes with a
bracket that accepts either a 1/4”
20 thread screw or rear stinger mount.
Individually Calibrated
The 3143B is individually calibrated at
10 m per ANSI C63.5 and calibrations
at 1m and 3m per SAE ARP 958.
